What is LPG?

LPG (Liquefied Petroleum Gas) is a mixture separated and extracted from gas fields or oil fields or liquidated from hydrocarbons in gas form produced in the refining process of crude oil., and iIt is classified into propane and butane products.

Propane products are mainly composed of propane (C3H8), and contain a small amount of methane, ethane and butane. In Korea, it is primarily used for cooking and heating at home, and as raw material for petrochemical industry, in addition to being used as raw material for urban gas.

Butane products are mostly composed of butane components such as normal butane (n-C4H10) and isobutane (i-C4H10), with some other ingredients such as propane. They are used as motor fuel as well as for heating and industrial purposes.

LPG Properties

  • 01

    Easy to transport
    and store

    Propane is easily liquefied if cooled at a temperature below -42.1°C under atmospheric pressure or applied with the pressure of 7 kg/cm² or above at room temperature, and butane can be more easily liquefied by cooling it at a temperature below -0.5°C or applied with pressure of 2 kg/cm² or above. Also, liquefaction of LPG at room temperature (15°C) results in a significant reduction in the volume of propane and butane by 1/260 and 1/230, respectively, which make it easier to transport and store.

  • 02

    Heavier than air
    but lighter than water

    LPG in gas form is 1.5-2.0 times heavier than air, and its liquefied form is 0.5 times lighter than water.

  • 03

    Colorless, odorless,
    and tasteless

    Pure LPG is colorless, odorless, and tasteless clean fuel that contains no toxic substances or impurities, but contains traces of substances with an odor that allow detection of leakage.

  • 04

    Clean and green energy

    LPG is chemically simple hydrocarbon and has a low carbon number which makes it susceptible to complete combustion. Due to the cleanliness of the fuel, LPG vehicles emit very little particulate matter (PM10), which are known to cause various respiratory and lung diseases, and generate a much lower level of nitrogen oxides, which are the main cause of secondary generation of particulate matter.
